The latest move in that vein happened Sunday when the Eagles announced the signing of former Penn State quarterback Christian Hackenberg. Hackenberg is a former second-round pick who has never appeared in an NFL game and is on his third team in four months.

While Hackenberg hasn't found any success as an NFL quarterback, there is some alluring potential there. He is a former five-star recruit who showed glimpses of ability during his freshman year in Houston Texans coach Bill O'Brien's pro-style offense at Penn State. But he didn't mesh with James Franklin's more spread-style that has suited Trace McSorley well.

So what does signing Hackenberg mean? It's a good question, especially with training camp set to break Tuesday and three more preseason games left on the schedule. Here's a look at what the Hackenberg signing means for each quarterback on the Eagles roster and the team as a whole.

Carson Wentz

Carson Wentz's place in the Eagles organization is safe, obviously. Coach Doug Pederson has said he is "married" to Wentz, and their futures are intertwined. When Wentz is healthy enough to return from his torn ACL and LCL -- whether that's Week 1 or later -- he'll be the team's starting quarterback. Wentz hasn't taken 11-on-11 reps during training camp since July 28, and it's not likely he'll play in the preseason. He's still aiming for a Week 1 return, while Pederson has been adamant Wentz's recovery is going to plan, and the Eagles don't want to expose Wentz to any hazards in practice.

Nick Foles

Much like Wentz, Nick Foles' place in the Eagles organization is safe. If Wentz isn't ready for the start of the season, Foles will continue to start. If Wentz is ready, Foles will be the backup and provide insurance against another injury. During last season's Super Bowl run, Foles showed the value of having a talented backup quarterback. Foles' contract expires after this season, and it seems likely that he'll test the open market and look for another starting job. The 29-year-old could be a sought after commodity in a quarterback-needy league, which would open up the No. 2 job behind Wentz. In terms of the immediate future, Foles didn't play in the first preseason game because of muscle spasms in his neck and right shoulder. He's returned to practice, but if he appears in a preseason game, it's likely it would be on an extremely limited basis. A series or two against New England on Thursday and then a similar workload next week against Cleveland before sitting out the finale against the Jets seems like a logical prediction for Foles.
